Dear Algebra 2 Students, Within this packet you will find mathematical concepts and skills learned in Algebra 1 that are the foundation from which Algebra 2 is built. These concepts need to be reviewed and practiced throughout the summer. The Algebra 2 course has recently undergone course design and curriculum changes making such review work important and essential for your success in Algebra 2. The Algebra 2 prerequisite packet will be due the first day of school. The packet will be graded and will count as a test grade. Your test grade will reflect both your effort (50%), which is based on attempting all problems and showing work for all problems, and accuracy (50%). The Algebra 2 prerequisite packet contains sample examples that have been done out for each concept, followed by Try these problems for you to complete.
